Whether you’re an avid collector or just interested in seeing some numismatic relics, the New Hampshire Coin & Currency Expo has hundreds of exhibit cases to explore. It’s happening Friday, June 12, from 10 a.m. to 7 p.m., and Saturday, June 13, from 9 a.m. to 6 p.m., at the Radisson Hotel in Manchester.

The expo has over 60 exhibitors and is the biggest multiple-day coin show in New England. People can expect to see coins and currency of various nations and eras, gold and silver, tokens, medals and stamps. There will also be free appraisals, educational seminars and open club meetings on both days of the show.

“People come both to buy and to look,” said Ernie Botte, coordinator of the event. “Some [exhibitors] are there for the primary reason of selling things, but there are [others] that are there more for people to talk to.”

Charles Browne, a former coin grader for the Professional Coin Grading Service, will give a one-hour presentation on coin grading. He’ll talk about how to look at a coin using the right magnifier and lighting, how marks and color can affect the coin’s value, what coin doctoring means and how to determine the grade on early American and foreign coins. The class will close with a 30-minute open discussion time.

Two clubs, The Barber Coin Collectors’ Society and the Liberty Seated Collectors Club, will hold a joint open meeting and offer information about their clubs and give an educational talk on 1861-O half dollars.

The Early American Coppers Club will also hold an open meeting and discussion on early U.S. copper coinage.

People are invited to bring their own collection items or new purchases from the expo for a show-and-tell time.

The popular Children’s Introduction to Coin Collecting seminar will be held again this year with John Kittredge of the Young Numismatist Program. Kids will have the chance to learn all the basics about coin collecting and grading. They’ll also walk away with some freebies donated by the program and expo dealers.

A highly visual presentation on fake coins will show different kinds of fakes, both counterfeit and altered, how to identify them and some of the most common ones.

In the exhibiting workshop, people can learn about how to best display their collections. Everyone participating in the workshop will walk around the expo, make notes of what they like and don’t like about each exhibit, then discuss with the group.

Lastly, historian and author David Taylor Moore will give a PowerPoint presentation on the Civil War. In the presentation, he will discuss the strategies and tactics used by both sides including weapons, technologies and leadership skills, and how those relate to today.

“If you’re interested in history, [the expo] is a good event to go to,” Botte said. “You can see money we used thousands of years ago, 50 years ago, all the way up to today.”
